Since power consumption is a big deal these days, we ran some simple power consumption tests on our test beds. The systems ran with the power supplies, case fans, video cards and hard drives. To measure idle usage, we ran the system at idle for one hour on the desktop with no screen saver and took the measurement. For load measurements, Prime95’s in-place large FFT’s were run on all cores to make sure each and every processor was at 100% load for maximum power consumption and heat. Curious about real world scenarios, we decided to drop Furmark and ran 3DMark 11 on the performance preset and took the maximum power consumption during the first GPU test.
Benchmark Results: The idle power consumption of the ASRock X79 Extreme9 is sitting at 103 Watts and was up there with the ASUS Rampage IV Extreme. Firing up 3DMark 11 the ASRock X79 Extreme9 pulled 239 Watts and 270 Watts under a full CPU load with Prime95.
